Abstract

The objectives of this study were to test the effects of different feed forms (S1-2), crude protein programs levels (feed programs P1-3) and their interaction in broiler diets on carcass quality and chemical composition of breast meat. In total 180 one-day old broiler chicks of the Indian River strain were used in the experimental with 6 treatments, 30 chicks each in 3 replicates of 10 chicks. The study consisted of a completely randomized experimental design with a 3 X 2 factorial arrangement of treatments and three program diets (P1-3), P1 (24, 23, 21, 20 and 19%) and P2 (23, 21, 20, and 19%) and P3 (21, 20, and 19%) crude protein respectively, with two feed forms (S1-2), S1 (crumbles/pellets) and S2 (crumbles) diets and their interaction. The experiment tested for 35 days of age and at d 35 of the feeding trial, two birds were selected from each replicate for carcass traits and chemical composition of breast meat. The results showed that all carcass traits weren’t affected by feed programs (P1-3), feed forms (S1-2) and their interaction except abdominal fat%. No significant influence of feed programs (P1-3), feed forms (S1-2) and their interaction on breast meat chemical composition (moisture, ash, ether extract and protein %). Conclusion: carcass traits and breast meat chemical composition haven’t been affected significantly by different feed programs, feed forms and their interaction except abdominal fat%.
